According to TW87 developers, this function can be applied on hybrid lines (formed by overhead lines and underground cables), provided that some restrictions are taken into account. Therefore, to evaluate the performance of the TW87 when applied to multi-section HLs, several faults in a 230 kV/60 Hz power system were simulated using the Alternative Transients Program (ATP). The results reveal that the restrictions proposed by the TW87 developers regarding the length and number of the HL cable sections guarantee the security of the TW87 operation.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121689970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This setup is accomplished using the reconfigurable I/O (RIO) architecture, which combines an FPGA and a real-time processor within one chip. The power system simulation is handled by real-time Electromagnetic Transients Program (EMTP) which is implemented in the FPGA, while a distance protection relay is implemented in the real-time processor and placed in a closed loop with the system being simulated. A graphical user interface is used to set the system parameters, including the conditions of an electric fault, and monitor the dynamic of a power system used as a case study. Offline simulations obtained from Matlab/Simulink are used to validate the real-time results.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129947789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, fast and reliable techniques for detection of incident and reflected fault-induced wave fronts have been increasingly reported in the literature. There are many filter technologies used on TW-based applications and, amongst them, the differentiator-smoother filter (DS filter) has shown to be promising compared to another one. Based on that, aiming to apply a reliable DS filter model in Alternative Transients Program (ATP) simulations during the study of TW-based solutions, this paper demonstrates the DS filter implementation using the ATP/MODELS language from tests using actual SEL-T400L relays, where the DS filter is embedded, the proposed ATP/MODELS DS filter function is validated. The obtained results show that the time response of the proposed ATP/MODELS filter block is the same of the actual one available in SEL-T400L relays, thereby it can accurately emulate the relay DS filter response during ATP studies.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131166038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective function is to minimize real power losses, operating costs, fixed costs and, consequently, to improve voltage quality. In this paper, two PSO algorithms are used, the first to determine the optimal capacitors allocation and the second one for optimal capacitors sizing. This algorithm has been executed on IEEE 34-bus and IEEE 85-bus radial distribution systems. The loads are considered as constant power loads. Results demonstrate effectiveness of the proposed alternative procedure PSO based algorithm.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124927492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method accuracy was evaluated through pole-to-ground fault scenarios for different fault positions and fault resistances. The obtained results reveal that the evaluated fault location method presents errors smaller than a conventional tower span (≈ 300 m). Also, in cases of uncertainties in line parameters, the method kept the same performance, since it is independent of the propagation velocities and line length.","PeriodicalId":148750,"journal":{"name":"2018 Workshop on Communication Networks and Power Systems (WCNPS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115198336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
